This will be an ongoing project that will be updated with new cables as and when I get them. I know a lot of people don’t believe in cable differences, but I personally believe in cables making a small difference, there are also ergonomic benefits from aftermarket cables. Cables are about synergy with the headphones you have too, and finding the right pairing is essential. Disclaimer: These cables were sent from the manufacturers for review, no incentive was given to write a favourable review. All opinions expressed are my own subjective findings. The Toxic Cables one is made by me from materials I purchased from Toxic Cables. All these cables are being used with my Inearz P350 custom monitors / 64 Audio U6 / Noble Sage Nobunaga Labs Medusa: Silver Plated Copper, 8 strands. http://nobunagalabs.com/nobunagalabs_premium/custom-recable/medusa/ Packaging, Build and Ergonomics: The Medusa comes in a fairly plain, clear plastic box, you can find the model name on the front and information (in Japanese) on the back of the box. It also has a polarity picture on the back, nothing special here. The build overall is good, the flat braid looks great, the y-split has a chin slider, but the jack lacks strain relief. I can see this being a weak point over time (should be easy enough to add some 3:1 heatshrink). Apart from that I cannot see any issues. Ergonomics are hit and miss, the flat braid is good, the cable is thin, but the sheathing is stiff and transmits a lot of cable noise. I find the cable noise is what really lets this cable down, I don’t think I’ve experienced a cable that is as noisy as this. On a personal preference note, I don’t like memory wire, these come with it but it’s easy to remove which slightly helps with the cable noise but does not fix it. Sound: The Medusa stays true to the common consensus on SPC cables, it increases the air and clarity, and tightens up the bass a little. I find that this cable brings out a little extra sparkle in the highs, and the bass isn’t as full. The bass becomes tighter, and more controlled, but this does come at a slight cost of slightly artificial timbre. Kick drums hit with less body, and vocals come across with a little less warmth than the stock cable. This cable does a great job of cleaning up the sound a little and bringing out added sparkle, it also adds a little width to the soundstage. Now I would say this is a brighter sounding cable vs stock, so it will pair better with warmer sounding IEM’s. Forza Audio Works Hybrid: 4 strands of 26AWG cryo 7N UPOCC copper + UPOCC silver http://forzaaudioworks.com/en/product.php?id_product=75 Packaging, Build Quality, Ergonomics: Packaging is great, a small card box full of wood shavings, holds a fabric pouch with the cable inside. A very attractive package, with a warranty card also included. The packaging helps protect the cable during shipping, and gives a premium feel when you open the parcel. Build quality is flawless, the braid is very even, the heat shrink very neat and a lovely, low profile carbon fibre y-split. It has a small piece of heat-shrink that acts as a chin slider, which is very handy. Ergonomics are excellent, it has the right balance between durability and flexibility. I Find it very comfortable to use for daily usage without getting in the way or feeling too heavy. It also coils nicely, and isn't too bulky to fit in a small storage case. I find angled connectors at the CIEM end to be very comfortable, it helps guide the cable behind the ear without uncomfortable memory wire. This cable does not emit cable noise, at least in my testing it didn't. Sound: This cable brings out a tiny bit more space and air in my P350, which when used with the stock cable are quite warm and relaxed. This cable makes them a little more lively and engaging without making them sound too bright or analytical. There is a little extra presence in the treble, with smoother, more refined lows. The lows are better separated and articulate, being also more precise. Essentially this cable keeps the stock sound, and just adds a little more air and separation, better control and just a hint of extra presence in the treble.
